Common sense is neither

"Common sense" is not ...

• common--two people can think totally opposing things and both call their ideas "common sense".
• sensible--from my experience, what you think is "common sense" is often wrong once you examine the subject more closely.

Don't be lazy and limit your thinking to what you feel is common sense. Be very careful to examine your opinions, seek out other people's perspectives--especially those who do a lot of thinking on the topic at hand, and keep your mind open. 

COMMON SENSE

What we believe to be
Common Sense
Is neither common nor sensical.
It is a compendium
of our life's experiences.
When next you are faced
with someone who has
'no common sense'
Seize the opportunity to share
your wisdom and experience
and to absorb theirs as well.
Such is the attitude
from which
Mutual Respect
is born. 

The above is just something I found on the Internets here
